What the specifications mean
Electronic shifting removes the usual shift cable but adds a separate battery and controls, while the 280% cassette range describes how much gearing is available. Carbon construction changes the inspection emphasis from metal-style dents and corrosion to impact damage, ripples and overtightened clamp areas. A threaded bottom bracket still requires the correct shell width, thread standard and crank-spindle interface before replacement.
Drivetrain
Electronic · 280% range
Shift-system battery state joins derailleur setup and sprocket compatibility as a troubleshooting variable.
Frame material
Carbon / composite
Look for impact damage and clamp marks rather than metal-style dents or rust.
Bottom bracket
Threaded interface
Shell width, thread standard and crank-spindle interface still require confirmation.

Frame size, pedals, tire setup and production substitutions can change the measured result.
Used-bike inspection
If you’re buying this bike used
Before any test ride: both brakes should stop the bike firmly and release cleanly; both wheels should run true and be securely attached; tires should have no casing damage; and the headset, handlebar, stem, cranks and pedals should have no looseness or play.
Follow the full used-bike inspection order →- FrameInspect the frame in bright light, especially around the head tube, bottom bracket, chainstays and clamped areas. Look for cracks, ripples, crushed sections or signs of a previous impact.Inspect the frame and fork →
- BrakesTest each brake separately and confirm it stops firmly and releases cleanly. Inspect the pads and braking surfaces for wear or contamination, and check the cables or hoses for damage.Inspect the brakes →
- DrivetrainConfirm every shift-system battery charges, every shift control works and the derailleur moves cleanly across the cassette. Make sure the matching shift-system charger is included, then measure chain wear and inspect the cassette teeth.Check drivetrain wear →
- Wheels & tiresSpin both wheels and watch the rims for side-to-side or vertical movement. Check for dents, cracks, loose or uneven spokes and hub play, then inspect both tire casings for cuts, cracking or exposed threads.Check wheels and tires →
- Bottom bracketTurn the cranks slowly, feel for rough bearings and check for side-to-side play. Creaking under load deserves investigation but does not identify the source by itself.Inspect the bottom bracket and shell →

Geometry interpretation
What this geometry means
420 geometry
Riding position
The 510 mm stack is low relative to the 370 mm reach, giving the frame a performance-oriented, lower-front-end proportion with more potential for a stretched riding position. A 75.5° seat angle puts the rider relatively forward over the bottom bracket, shortening the effective seated reach compared with a more relaxed seat angle.
Handling tendencies
The 70.6° head angle points to more stability-oriented steering geometry. Head angle is only one part of steering feel; fork offset, trail, wheel size and cockpit setup also matter. A 72 mm bottom-bracket drop places the rider relatively low between the wheels, which can add a settled cornering feel while reducing pedal clearance compared with a higher bottom bracket.
Archive context
The chainstay of 408 mm sits somewhat shorter than typical. The seat angle of 75.5° sits somewhat steeper than typical. The head angle of 70.6° sits close to the middle of the group.
455 geometry
Riding position
The 522 mm stack is low relative to the 375 mm reach, giving the frame a performance-oriented, lower-front-end proportion with more potential for a stretched riding position. A 75° seat angle puts the rider relatively forward over the bottom bracket, shortening the effective seated reach compared with a more relaxed seat angle.
Handling tendencies
The 71° head angle points to more stability-oriented steering geometry. Head angle is only one part of steering feel; fork offset, trail, wheel size and cockpit setup also matter. A 72 mm bottom-bracket drop places the rider relatively low between the wheels, which can add a settled cornering feel while reducing pedal clearance compared with a higher bottom bracket.
Archive context
The chainstay of 408 mm sits somewhat shorter than typical. Its bottom-bracket drop of 72 mm sits somewhat shallower than typical. The seat angle of 75° sits somewhat steeper than typical.
485 geometry
Riding position
The 539 mm stack is low relative to the 383 mm reach, giving the frame a performance-oriented, lower-front-end proportion with more potential for a stretched riding position. A 74.5° seat angle puts the rider relatively forward over the bottom bracket, shortening the effective seated reach compared with a more relaxed seat angle.
Handling tendencies
The 71.5° head angle points to more stability-oriented steering geometry. Head angle is only one part of steering feel; fork offset, trail, wheel size and cockpit setup also matter. A 72 mm bottom-bracket drop places the rider relatively low between the wheels, which can add a settled cornering feel while reducing pedal clearance compared with a higher bottom bracket.
Archive context
The chainstay of 408 mm sits somewhat shorter than typical. Its reach of 383 mm sits somewhat longer than typical. Its bottom-bracket drop of 72 mm sits somewhat shallower than typical.
510 geometry
Handling tendencies
The 71.8° head angle points to more stability-oriented steering geometry. Head angle is only one part of steering feel; fork offset, trail, wheel size and cockpit setup also matter. A 72 mm bottom-bracket drop places the rider relatively low between the wheels, which can add a settled cornering feel while reducing pedal clearance compared with a higher bottom bracket.
Archive context
The head angle of 71.8° sits toward the slacker end. The chainstay of 408 mm sits somewhat shorter than typical. Its reach of 388 mm sits somewhat longer than typical.
530 geometry
Riding position
The 395 mm reach and 575 mm stack form a moderate road-bike proportion, balancing cockpit length with front-end height rather than pushing to an extreme race-low or endurance-upright shape.
Handling tendencies
The 72.5° head angle points to moderate and balanced steering geometry. Head angle is only one part of steering feel; fork offset, trail, wheel size and cockpit setup also matter. A 72 mm bottom-bracket drop places the rider relatively low between the wheels, which can add a settled cornering feel while reducing pedal clearance compared with a higher bottom bracket.
Archive context
The chainstay of 408 mm sits somewhat shorter than typical. Its reach of 395 mm sits somewhat longer than typical. The head angle of 72.5° sits somewhat slacker than typical.
550 geometry
Riding position
The 403 mm reach and 593 mm stack form a moderate road-bike proportion, balancing cockpit length with front-end height rather than pushing to an extreme race-low or endurance-upright shape.
Handling tendencies
The 72.9° head angle points to moderate and balanced steering geometry. Head angle is only one part of steering feel; fork offset, trail, wheel size and cockpit setup also matter. A 72 mm bottom-bracket drop places the rider relatively low between the wheels, which can add a settled cornering feel while reducing pedal clearance compared with a higher bottom bracket.
Archive context
The chainstay of 408 mm sits somewhat shorter than typical. Its reach of 403 mm sits somewhat longer than typical. The seat angle of 73° sits somewhat more relaxed than typical.
570 geometry
Riding position
The 410 mm reach and 612 mm stack form a moderate road-bike proportion, balancing cockpit length with front-end height rather than pushing to an extreme race-low or endurance-upright shape.
Handling tendencies
The 73.1° head angle points to moderate and balanced steering geometry. Head angle is only one part of steering feel; fork offset, trail, wheel size and cockpit setup also matter. A 72 mm bottom-bracket drop places the rider relatively low between the wheels, which can add a settled cornering feel while reducing pedal clearance compared with a higher bottom bracket.
Archive context
Its reach of 410 mm sits toward the longer end. The chainstay of 408 mm sits toward the shorter rear-center end. Its stack of 612 mm sits somewhat lower than typical.
Across the size range
From 420 to 570, reach grows by 40 mm and stack by 102 mm, showing how the frame becomes both longer and taller through the published size range. The rear center stays essentially constant at about 408 mm across sizes, so most of the wheelbase growth happens in the front half of the bike rather than by lengthening the rear triangle.
Geometry describes frame proportions and likely tendencies, not a ride test. Rider proportions, cockpit setup, tires, suspension settings, wheel configuration, and component choices can materially change how a bicycle fits and feels.
